چکیده انگلیسی
Elaborate design of high-performance anode materials is of vital significance for lithium-ion batteries (LIBs). Herein, carbon-coated MoO3 nanorods decorated with WO2 nanoparticles (MoO3/WO2@C), a novel structured nanohybrid in which MoO3 nanorods are encapsulated by the amorphous carbon layer and decorated with ultrasmall WO2 nanoparticles, have been successfully synthesized via a facile one-step hydrothermal method. When evaluated as the anode materials for LIBs, the effects of different carbon contents in the as-obtained MoO3/WO2@C nanomaterials on the lithium-ion storage properties are investigated. Results show that the MoO3/WO2@C nanocomposite with the optimized carbon content delivers a high reversible capacity of 815â¯mAh·gâ1 after 100 cycles at 0.05â¯C and an ultrastable capacity of 80â¯mAh·gâ1 at least 5000 cycles at the current density of 1â¯C.
